Outline of Final Research Achievements

We propose two speech enhancement methods for hearing aid. The first is the method combining image information captured by camera and audio information captured by microphone array. Experiment results show that the performance with the proposed method using microphone array and camera is superior to the system only with microphone array. The second method uses the Multichannel Nonnegative Matrix Factorization (MNMF) for speech enhancement. The problem of MNMF is initial-value dependency for the performance. In experimental results, the initial-value settings based on the phase differences between the microphones was more effective than the random settings
